Decoherence Induced by the Environment for Dimerized Anisotropic XY Spin Chain

Abstract: The Loschmidt echo of single qubit coupling to the environment for dimerized anisotropic XY spin chain in transverse field have been analyzed. We have obtained analytical expression for the Loschmidt echo. By numerically computing the Loschmidt echo, we find that the decay of coherence will be enhanced with the increasing of the staggered parameter.

“…The NDSI threshold is the most important factor affecting the result accuracy. Based on the previous results [7] , through repeated tests and combined with the actual situation of Urumqi Glacier No.1 and visual interpretation results, it is believed that the NDSI threshold of 0.75 ~ 0.96 is suitable for area.…”

“…For instance, in the Normalized Difference Snow Index (NDSI). With the threshold value of 0.57≤NDSI≤0.72 is set to identify the range of snow cover [7]. The third one is the single-band threshold method where the gray threshold value of 90~160 in the Thematic Mapper(TM)4 band is set to extract the snow cover range [8].…”

“…Some of the advantages include low cost, high efficiency, minimization of sludge production, possibility of regeneration of biosorbent and metal recovery [7,9]. Biosorption is therefore seen as an alternative method that can be categorized as a green technology for heavy metal removal from industrial effluents [10]. Different parts of plants and their related wastes are naturally available as well as inexpensive in comparison to other chemically modified materials.…”
